South Dakota primary and local election preview

South Dakota News Watch

For a non-presidential election year, 2026 has the makings of one of those political seasons that South Dakotans talk about years or even decades to come.

Advertising and communication in a contentious Republican race for governor has dominated airwaves, social media feeds and text notifications. But because of a law change that puts many local contests on Tuesday’s ballot, more than just the party faithful have something at stake in a lot of places across the state.

Find out which district you live in through the South Dakota Secretary of State website and also see the list of candidates you can vote for as well as a sample ballot, though it may not include all local races.

Early and absentee voting started last month, but if you’re early voting Monday or going to the polls Tuesday, here’s a summary of the key races along with links to South Dakota News Watch’s coverage.

Top row from left: South Dakota GOP gubernatorial candidates Toby Doeden, Jon Hansen, Dusty Johnson and Larry Rhoden. Bottom row from left: Senate candidates Mike Rounds and Justin McNeal; House candidates Marty Jackley and James Bialota.

South Dakota governor

Four Republicans are running to represent the party and meet Democratic candidate Dan Ahlers in the Nov. 3 general election nomination. Here are the Republican candidates with links to profiles by News Watch’s Alexander Rifaat:

If Doeden, Hansen, Johnson or Rhoden doesn’t receive 35% of the vote in the Republican primary, a runoff election between the two top vote-getters will be held eight weeks later, on July 28.

US Senate

U.S. Sen. Mike Rounds, one of two U.S. senators in Congress from South Dakota, is up for re-election this year.

Republican voters in Tuesday’s primary are choosing between him and challenger Justin McNeal. The winner will meet Democrat Julian Beaudion and Independent Brian Bengs in the Nov. 3 general election.

US House of Representatives

When Johnson opted to run for governor, it opened up South Dakota’s only seat in the U.S. House of Representatives.

Republican voters on Tuesday will choose between Attorney General Marty Jackley and James Bialota Jr., and the winner will meet Democrat Nicole Gronli in the Nov. 3 general election.

Local races

A new South Dakota law about municipal election dates added a lot of races to ballots for many voters, but it also means many non-partisan voters have something to vote on Tuesday.

That includes in Sioux Falls, where the city’s municipal elections used to be held in April. Voters will be choosing a new mayor, city council members and school board members Tuesday.

Elsewhere in the state, local ballots include positions like county commissioners, auditor, sheriff and the register of deeds.
